Coastal Oceanography

Circulation

Australia is an island continent surrounded by boundary currents, which include: Hiri (HiC), East Australian (EAC), Zeehan (ZC), Flinders (FC), Leeuwin (LC) and Holloway (HC) currents. The EAC is the major western boundary current consisting of a large mesoscale eddy field whilst the LC is a poleward flowing eastern boundary current with a connection to the north of Australia through the HC and to the south via ZC. A high resolution (2–4 km) ROMS (Regional Ocean Modelling System) model was configured for the entire Australian continental shelf and slope together with the adjacent deep ocean region. Multi-year simulations have been completed to examine the interannual variability of the ocean transports around Australia.
